Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2023-1073)
The vulnerability allows an attacker to compromise the affected system.
The vulnerability exists due to a boundary error in the Linux kernel human interface device (HID) subsystem. An attacker with physical access to the system can insert in a specific way malicious USB device, trigger memory corruption and execute arbitrary code.
2) Buffer overflow (CVE-ID: CVE-2023-45871)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the IGB driver in drivers/net/ethernet/intel/igb/igb_main.c when handling frames larger than the MTU. A remote attacker can send specially crafted traffic to the system, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) NULL pointer dereference (CVE-ID: CVE-2023-6356)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the nvmet_tcp_build_iovec() function in the Linux kernel's NVMe driver. A remote attacker can pass specially crafted TCP packets to the system and perform a denial of service (DoS) attack.
4) NULL pointer dereference (CVE-ID: CVE-2023-6535)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the nvmet_tcp_execute_request() function in the Linux kernel's NVMe driver. A remote attacker can send specially crafted NVMe-oF/TCP packets to the system and perform a denial of service (DoS) attack.
5) NULL pointer dereference (CVE-ID: CVE-2023-6536)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the __nvmet_req_complete() function in the Linux kernel's NVMe driver. A remote attacker can send specially crafted NVMe-oF/TCP packets to the system and perform a denial of service (DoS) attack.
6) Resource exhaustion (CVE-ID: CVE-2023-1206)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a hash collision flaw in the IPv6 connection lookup table in the Linux kernel’s IPv6 functionality when an attacker makes a new kind of SYN flood attack. A remote attacker can increase the CPU usage of the server that accepts IPV6 connections up to 95%.
7) Use-after-free (CVE-ID: CVE-2023-5178)
The vulnerability allows a local authenticated user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the drivers/nvme/target/tcp.c in nvmet_tcp_free_crypto due to a logical bug in the NVMe-oF/TCP subsystem in the Linux kernel. A local authenticated user can trigger a use-after-free error and escalate privileges on the system.
